To provide a separator for a fuel cell and a fuel cell which solve the problem of decrease of reaction area due to carbon dioxide gas at the fuel electrode side and gas passage closure by the generated water at the oxidizer electrode side, and uses a liquid fuel capable of application to a portable equipment or the like.
This is a fuel cell separator in which a fuel electrode 12 and an oxidizer electrode 13 are installed on both sides and which is arranged in a solid polyelectrolyte layer 11 and in which passage grooves 15, 16 for supplying respectively the fuel and the oxidizer are formed. One or a plurality of pieces of passage grooves 15, 16 are arranged in parallel in zigzag line on an identical surface and the passage groove 15 in which the fuel is supplied is formed so that the fuel may flow from the upper part toward the lower part, and the passage groove 16 in which the oxidizer gas is supplied is formed so that the oxidizer gas may flow from the upper part toward the lower part.
